I 1 3 wue wroz 46 x 4% W Z, M

W 4'6 Mid. f 3% 4 atto'cwma 11 is attached to the conical shell 12 by means of the bolts 13, 13. An angular annular extension 14 of the shell 11. supports a fixed foraminous plate 15. The upper portion of'the shell 11 carries a series of outwardly extended lugs 16, 16. An annular member 18, capable of abutmentupon the foraminous plate 17, has an outwardly extended annular flange 19. The thumbscrew bolts 20, 20 extend throughholes in the flange 19 and mesh with the'threads in threaded holes in the lugs 16, 16. The plates 7 15 and 17 may thus be maintained at any desired distance from each other. A pipe 21 connects the upper portion of the chamber within theshell 11 to the top of a reserve tank 22. The bottom of the tank 22 'is connected by the pipe 23, carrying the valve 24, with the intake 'pipe 25 of the pump 26. The exit pipe 27 of the pump 26 is attached to the lower part of the shell 12 by the bolts 28, 28.v The pipe 25 is connected by the pipe 29, carrying the valve 30, with a dye dissolving tank, not shown. The pipe29 is also connected with the pipe 32 carrying the valve 33, pipe 32. being-connected to a water supply source. A. perforate steam pipe 31 is within the lower portion of the chamber of shell 11 and beneath the foraminous plate 15. The pipe 27 is connected to a drain or receivingrec'eptacle chamber between the foraminous plates 15 v and 17 as the dyeing chamber 39, the charm ber within the shell 12 as the equalizing chamber 40, and the chamber within the exit pipe '27 of the pump 26 as the pump chamber 41. v

lVithin the equalizing chamber 40 is an upwardly and downwardly extended conical shaped member 42,so situated that the pressureof any liquid discharged into the chamber by means of the pump 26 will be distributed equally throughout and hence be impinged uniformly upon the entire bottom of the foraminous plate 15. Extending outwardly from the conical member 42 to the shell 12 is a series of vertical plates 43,43,

which serve to support the member 42 and to aid the distribution of the liquid within the equalizing chamber-40.

Within the shell 11 is a conduit or channel 47 connecting the interior of the device below the plate 17 with the small device 48.

This connection is made by the pipe 49 threaded in the top of the conduit 47, the pipe 49. being joined to the pipe 50 by the swivel joint 51. The pipe 50 is connected to the thermometer 52 by the pipe 53, the liquid afterpassing the thermometer passing through the pipe 54 into the top chamber 38. The small device 48 is exactly simi lar and proportionate to the large device in every particular, and the liquidentering in through the pipe 50 leaves it through the pipe 55 into the top chamber 38. The pipe 49 carries the valve 56. The device 48 can be revolved upon the joint 51 into the position indicated in dotted lines,in order to remove it from above the larger device when it is desired to remove or introduce the foraniinous plate 17. I s

By means of this construction, the condi tion of the fiber in the large dyeing chamber 39 may be determined at any time without interruptirg the operation, opening the large device or displacing the fiber therein, by closing the valve 56 and examining the fiber in the small device 48.

The operation of the device is as follows: The goods to be dyed are placed upon the plate 15 and the foraminous plate 17 inserted thereon. The annular member 18 is then introduced and pressed downwardly by means of the thumb-screw bolts 20, 20. until the goods are in a proper condition of compression. All of the valves are closed with the exception of valves 30 and 56. The pump 26 is started, and the dye liquor passes downwardly through the pipe 29 into the pump 26, and is forced upwardly through the entire device and the goods contained therein, the operation inthe smaller device being'the same as in the larger. TVhen sufficient dye liquor has been introduced, valve 30 is closed and valve24 is opened, and the operationof the pump thus causes a continu ous circulation of the dye liquor through the device and the goods contained therein, the conical member 42 with its attachments causing a uniform pressure of liquid upon the plate 15, and the formation of the foraminous plate causinga uniform treatment of .the goods. in the dyeing chamber. The foraminous plate 17 maintains an equal pressure throughout the mass of goods, as

its perforations are the same as those in the plate 15. a

When the dyeing operation is completed the pump is stopped and all the valves are placed in a closedcondition except valves 35 and 56, when all the liquor in the device will be drained off. Valve 35 is then closed, pipe 21 connected with a drain, valve 33 opened and the pump, started, by this means fresh water is forced through the device and the goods thoroughly and uniformly washed.

In the modification shown in Figs. 6 and 7 the conical shaped member 42 is supported 1 gevatsac to theshell 12 by the diamond shaped *bars 44,

In the modification shown in Figs. 8, 9 and 10, 516 fcraminous plates comprise '3 Series df upwardly and downw rdly extended serratedpuamidalbars 45, 45 having longit udinal openings-4'6, 46,
